The Guardian's new ICM poll of Liberal Democrat target seats (possibly the first such study of these seats) came out yesterday evening. It looked at the first 42 seats seats where the Lib Dems need a swing of up to 6% to win.

Two weeks ago, the Telegraph ran a column by Frank Field entitled: 'Why is there no talk about immigration?'. The answer may have now come to light, as the Sunday Telegraph seems to have failed to highlight findings from its own polling.

More discussion this morning from commentators trying to make sense of the ongoing disparity of poll results in today’s Sunday Papers:

BPIX (Mail on Sunday) Con: 34, Lab 26, LD 30, Other 10

YouGov (Sunday Times) Con: 35, Lab 27, LD 28, Other 10

ICM (Sun Tel) Con: 35, Lab 26, LD 31, Other 8

OnePoll (People) Con: 32, Lab 23, LD 32, Other 13

IPSOS MORI (News of the World) Con 36, Lab 30, LD 23, Other 11

ComRes (Indy on Sunday and Mirror) Con: 34, Lab 28, LD 29, Other 9

To add to the complexity, YouGov polling in the Lab-Con marginals shows the Tories slipping to 34%. Labour is on 35% and the Lib Dems have jumped to 26%. This still represents a pro-Conservative swing, because of the drop in Labour support, but of only 4%, in line with the overall national swing. It would give the Tories 57 of these seats, not enough for a majority.
